IMPLANTABLE DEVICES AND METHODS FOR TREATING MICRO-ARCHITECTURE DETERIORATION OF BONE TISSUE |
摘要 |
An expandable stabilization device is disclosed that is suitable for deployment within cancellous bone, including, for example, within a vertebral body of a spine. The device comprises: an elongate expandable shaft adapted to be positioned within a vertebral body having a first profile and a second profile; wherein the shaft is adapted to cut through cancellous bone within the vertebral body during expansion from the first profile to the second profile; and further wherein the shaft is adapted to abut a surface of cortical bone within the vertebral body without passing therethrough. The invention also includes a method for treating cancellous bone, such as cancellous bone of a vertebral body. The method comprises: delivering an expandable device within the cancellous bone of in an interior of a vertebral body; expanding the delivered device within the cancellous bone of the vertebra body; applying force from a surface of the device to an inner surface of a cancellous bone of the vertebral body sufficient to cut through the cancellous bone; and applying force from a surface of the device to an inner surface of a cortical bone of the vertebral body sufficient to support the vertebral body.
